Model Aircraft Control Model and Six-Degree-of-Freedom Simulation

This technical documentation presents the implementation of two sophisticated simulation models: an aircraft control model and a six-degree-of-freedom (6DOF) flight dynamics model. The development follows rigorous mathematical formulations from the authoritative text "Aircraft Flight Dynamics," incorporating essential aerodynamic principles and motion physics. The implementation involves sophisticated numerical integration techniques for solving equations of motion, with modules handling aerodynamic coefficients, control surface deflections, and environmental factors. Key algorithms include quaternion-based attitude representation for avoiding gimbal lock in the 6DOF model and PID control loops for aircraft stabilization. The models feature comprehensive aerodynamic calculations using coefficient-based approaches, where lift, drag, and moment coefficients are dynamically computed based on angle of attack, sideslip, and control inputs. The implementation includes MATLAB/Simulink blocks for real-time simulation and parameter tuning capabilities. Extensive validation through flight envelope testing and comparison with experimental data ensures model fidelity. These simulations have been successfully applied in aircraft design optimization, autopilot development, and pilot training systems, providing high-accuracy predictions of aircraft behavior across various flight conditions. The code architecture employs modular design with separate components for aerodynamics, propulsion, controls, and environment, allowing for easy customization and integration with hardware-in-the-loop systems.
